How to Run Ethernet Cable Through Old Homes


Running ethernet cable through an old home can seem daunting, but with some planning and the right tools, it's very doable as a DIY project. Ethernet cable allows you to connect devices like computers, smart TVs, game consoles, and printers to your home network and router for fast, reliable connectivity. While WiFi can also provide internet access, ethernet cables offer superior speeds and stability. This guide will walk you through everything I needed to know to successfully run ethernet cables through my old house.

Gather Information and Make a Plan

The first step is to survey your home to understand the layout and determine the best routing for the ethernet cables.

Once you've mapped out potential routes, mark where the ethernet runs would start and end. You'll terminate them in jacks mounted on walls or in floor boxes. Finally, decide on a central spot to locate your network hardware like a router, switch, and modem. This will be the hub that all ethernet runs connect back to.

Gather Supplies

Before getting started, ensure you have all the right supplies on hand:

Running Cables Through Walls

The trickiest part is routing cables through interior walls vertically between floors or horizontally between rooms. Here are some best practices:

Running Cables Through Attics and Basements

Attics and basements offer more flexibility for routing ethernet cable since utilities are not contained within the open framing:

Connecting and Terminating Cables

Once all the physical cable pulls are complete, the ethernet cables need to be properly terminated at both ends:

Finally, connect all the home runs back to a central switch or router in the designated networking closet or panel.

Final Thoughts

Running ethernet cables yourself requires planning, patience, and care to avoid damage, but it can be very rewarding. The investment of time upfront to neatly route and terminate cables is well worth it for the performance and stability gains. Take things slow, leverage existing pathways where possible, and be mindful of building codes. Your wired home network will be up and running smoothly in no time!
